Description

Technical Field

[0001] The utility model relates to the field of antenna equipment, in particular to a foldable array antenna. Background Art

[0002] Signal receiving antenna devices usually adopt a single antenna, dual antenna or quad antenna structure. The installation method of the signal receiving antenna will vary greatly in different usage scenarios. In most occasions where it is not frequently disassembled and assembled, a fixed installation is usually adopted. The structure is simple and easy to implement, but the existing antenna cannot be quickly folded and stored.

[0003] According to the existing patent document with publication number CN210723374U, a foldable antenna source array is disclosed, which includes an antenna body, a switch unit arranged on the antenna body, and a plurality of first antenna groups for receiving or transmitting electromagnetic waves in a first frequency band, which are hingedly arranged at equal intervals on the outer wall of the antenna body and electrically connected to the switch unit. Each of the first antenna groups includes a folding rod group and a radiation rod group. One end of the folding rod group is hingedly mounted on the outer wall of the antenna body. When in use, this technical solution makes the folding rod group fit together with the outer wall of the antenna body to form a folded state of the folding rod group. The radiation rod group hinged to the folding rod group can also rotate around the hinge at which the folding rod group is hinged, so that the radiation rod group fits together with the folding rod group to form a folded state of the radiation rod group. The foldable structure of the folding rod group and the radiation rod group greatly reduces the volume of the foldable antenna source array. With respect to the above technical solution, although this solution realizes the folding of the antenna, it is impossible to limit and fix the antenna after folding, which is inconvenient during use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a foldable array antenna to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. When in use, the support rod is rotated 90 degrees through the fixed rod and then contacts the ring seat. After the ring seat is rotated, the opening is aligned with the support rod. After the support rod is installed inside the limit groove through the opening, the ring seat returns to its position to limit the support rod up and down.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solution: a foldable array antenna, including a fixing base, a fixing groove is provided on the fixing base, a fixing rod is movably installed inside the fixing groove, a support rod is welded on the fixing rod, a groove is provided on the inner wall of the support rod, a first receiving mechanism is fixedly installed inside the groove, an annular groove is provided inside the fixing base, a ring seat is rotatably installed inside the ring groove, and a second receiving mechanism is fixedly installed on the ring seat.

[0006] Furthermore, an opening is provided on the ring seat, and a limiting groove is provided at one end of the opening, and the limiting groove cooperates with the support rod.

[0007] Furthermore, a fixing tube is fixed on the fixing rod, a rotating column is movably installed inside the fixing tube, and a torsion spring is installed on the rotating column.

[0008] Furthermore, both ends of the torsion spring are fixedly mounted on the rotating column and the inner wall of the fixed tube respectively, and one end of the rotating column is fixed on the inner wall of the fixed groove.

[0009] Furthermore, an arc-shaped groove is formed on the inner wall of the annular groove, a supporting mechanism is fixed inside the arc-shaped groove, and a fixing column is fixed at one end of the supporting mechanism.

[0010] Furthermore, one end of the fixing column is fixed inside the ring seat, and one end of the fixing column is fixed to a limiting disk.

[0011] Beneficial effects of the utility model:

[0012] 1. This is a foldable array antenna. When in use, the support rod is rotated 90 degrees through the fixed rod and then contacts the ring seat. After the ring seat is rotated, the opening is aligned with the support rod. After the support rod is installed inside the limit groove through the opening, the ring seat returns to its position to limit the support rod up and down.

[0013] 2. This is a foldable array antenna, in which the first receiving mechanism is installed inside the slot. Later, the first receiving mechanism is folded and shielded after being shielded by the support rod to avoid damage to the first receiving mechanism caused by external force. The first receiving mechanism and the second receiving mechanism are cross-distributed, thereby realizing multi-point reception of signals. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a foldable array antenna, comprising a fixing seat 1, a fixing groove 2 is provided on the fixing seat 1, a fixing rod 3 is movably installed inside the fixing groove 2, a support rod 4 is welded on the fixing rod 3, a slot 5 is provided on the inner wall of the support rod 4, a first receiving mechanism 6 is fixedly installed inside the slot 5, a ring groove 14 is provided inside the fixing seat 1, a ring seat 7 is rotatably installed inside the ring groove 14, a second receiving mechanism 8 is fixedly installed on the ring seat 7, an opening 9 is provided on the ring seat 7, a limiting groove 10 is provided at one end of the opening 9, the limiting groove 10 cooperates with the support rod 4, the first receiving mechanism 6 and the second receiving mechanism 8 are both receiving antennas, and multi-point reception of signals is performed through the staggered distribution of the first receiving mechanism 6 and the second receiving mechanism 8.

[0021] In this embodiment, a fixed tube 11 is fixed on the fixed rod 3, and a rotating column 12 is movably installed inside the fixed tube 11. A torsion spring 13 is installed on the rotating column 12, and both ends of the torsion spring 13 are respectively fixedly installed on the rotating column 12 and the inner wall of the fixed tube 11. One end of the rotating column 12 is fixed on the inner wall of the fixed groove 2, and an arc groove 15 is opened on the inner wall of the annular groove 14. A supporting mechanism 16 is fixed inside the arc groove 15, and a fixed column 17 is fixed at one end of the supporting mechanism 16. One end of the fixed column 17 is fixed to the inside of the ring seat 7, and a limiting disk 18 is fixed at one end of the fixed column 17. The supporting mechanism 16 is a supporting spring, and the supporting spring pushes the fixed column 17 to return to one end of the arc groove 15, thereby realizing the return of the ring seat 7 after rotation.

[0022] When the device is in use, the fixing seat 1 is fixedly installed in the use of a child. After the fixing seat 1 is fixedly installed, the ring seat 7 is rotated inside the ring groove 14. The rotation causes the support rod 4 to move from the limit groove 10 to the inside of the opening 9. The elastic force generated by the torsion spring 13 causes the fixing rod 3 to drive the support rod 4 to rotate upward, and the support rod 4 is taken out from the inside of the opening 9 when it rotates. After the support rod 4 rotates 90 degrees, the first receiving mechanism 6 is opened for use. When in use, the first receiving mechanism 6 and the second receiving mechanism 8 are cross-staggered and distributed. Multi-point comprehensive reception of signals is achieved through the first receiving mechanism 6 and the second receiving mechanism 8. When the support rod 4 needs to be folded and stored, the support rod 4 contacts the ring seat 7 after rotating 90 degrees through the fixing rod 3. After the ring seat 7 rotates, the opening 9 is aligned with the support rod 4. After the support rod 4 is installed inside the limit groove 10 through the opening 9, the supporting mechanism 16 pushes the fixing column 17 and the ring seat 7 back into place. After the ring seat 7 is returned, the limit groove 10 limits the support rod 4 up and down.
